What are Characteristics Of Constructors in C++

Characteristics of constructors are below:-

  •  These are called automatically when the objects are created.
  • All objects of the class having a constructor are initialized before some use.
  • These should be declared in the public section for availability to all the functions.
  •  Return type (not even void) cannot be specified for constructors.
  • These cannot be inherited, but a derived class can call the base class constructor.
  • These cannot be static.
  • Default and copy constructors are generated by the compiler wherever required.
  • Generated constructors are public.
  • These can have default arguments as other C++ functions.
  •  A constructor can call member functions of its class.
  • An object of a class with a constructor cannot be used as a member of a union.
  • A constructor can call member functions of its class.
  • We can use a constructor to create new objects of its class and constructors cannot be virtual.
